SQUARE FOR TOOLS.

Specification of Letters Patent.

Patented Apr. 29, 191mb Application filed .T une 22, 1917. Serial No. 176,409.

To all whom it 'may concern:

Be it known that T, ROBERT H. Bann, a citizen of the United States, residing at Kelso, in the county of Oowlitz, State of lashingtoin have invented a new and useful Square for Tools; and T do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to improvements in squares for tools and the like.

One of its objects is the provision of a square blade for use in connection with a tool blade, whereby two tools may be made in one article.

Another object of the invention is the provision of a square blade pivoted on the tool blade, so that when the square blade is thrown at right angles to the tool blade, a carpenters square is fo-rmed.

Still another object of the invention is to provide means for limiting the square blade to a right-angled position with one of the edges of the tool blade.

Still another object of the invention is to provide the handle of the tool blade with a pocket formed between a part of the handle and the tool blade, whereby the square blade, when not in use, may be folded into the pocket, there being means for holding said squareblade in the pocket.

Still another object of the invention is the provision of means for holding the square blade at various angular positions between the right-angled position, so that it may be used in laying off bevels.

Still another object of the invention is to provide the handle of the tool blade with -level glasses, whereby the tool blade may be used as a bevel for horizontal and vertical objects. 4

Other objects will appear in the detailed description which follows:

It is to be understood that the invention is not to be conned to the exact construction herein disclosed, the right being reserved to make any changes or alterations falling within the scope of what is claimed.

In the drawings:

Figure 1 is a view in side elevation, showing a tool blade which is provided with a handle having a pocket for the reception of a square blade, which square blade is pivotally mounted upon the tool blade.

Fig. 2 is a view in side elevation of the toolblade, showing the square blade open.

Fig. 3 is a view partly in section and partly in elevation, of a portion of the tool blade and its handle, showing the square blade open and showing the pocket for the square blade. This View is enlarged Fig. l is a section on the line 4 4 of Fig. 1. This view is also enlarged.

Referring to the drawings, 1 designates a tool blade, preferably a saw blade. The edge 2 of this blade is provided with graduations 3, whereby the straight edge of the tool may be used as a rule. The tool blade 1 has a handle 4 intoa recess 5 of which the blade is secured by the rivets 6. One wall of this recess 5 is cut away providing a pocket 7 for the reception of the blade 8 which is pivoted at one end on a riveted pin 9 attached near the upper end of the pocket 7. The blade 8 is provided with graduations 10 and near its pivoted end has a lateral projection 11 made integral with it and adapted to move over the graduations 12 formed on an arc concentric with the pin 9. When the blade is open its back edge contacts with a pin 13 set in lthe handle el close to the upper end of the pocket 7, this pin limiting the blade 8 to the right angled position with reference to the edge 2. The bottom of the pocket 7 is cut away, as indi cated at 11i Fig. 3 to provide a space for the lateral projection 11 when the blade 8 is folded into the pocket. This cut away portion 14 is formed on an arc concentric with the pivot pin 9, so that the projection 11 may freely enter as the blade 8 is being folded in.

When the blade 8 is not in use and is folded into the pocket 7 it is secured therein by a pin 15 which extends through one wall of the pocket 7 and enters a hole 16 formed in the tool blade 8. The pin 15 is suitably secured to a spring plate 17 attached on the outside of the handle 4L by means of rivets 18. The pivoted end of the tool blade 8 is made concentric with the pivot pin 9 and is provided with a series of uniformly spaced semi-circular recesses 19. These recesses 19 have the same angular positions with reference to each other that the graduations l2 have with respect to each other and any one may be engaged by the pin l5, so that the blade S may be held in various angular positions relative to the edge Q, any desired angle being indicated by the lateral projection l1 which points to the desired angle upon the graduations l2.

rllhe free end of the blade S is provided With a laterally extending flange 2O which may be engaged by the thumb so as to thro \v the blade 8 open.

The handle 4 of the tool blade is provided with level glasses 2l, ivhereby the tool blade may be used for vertical and horizontal leveling.

This application supersedes the application, filed September 27, 1915, Serial Number 122,418 and sets forth improved features of construction over the device then shown and described.

That is claimed is:

4l. In a square, a blade having graduated Straight edge, a handle having an edge portion inclined at an obtuse angle to the straight edge, said handle being provided with a recess in Which one end of said blade is secured, said handle having a. pocket adjoining the recess, a second blade having graduations and having one end pivoted insaid pocket, whereby the blade may enter the pocket or may be thrown open at right angles to the straight edge, thereby constituting a square, a pin at one end of the pocket to be engaged by the edge of the f Copies of this patent may be obtained for second blade for limiting' the second blade at right angles to the straight edge, and means carried by the handle and provided with a device extending through thevvall of the pocket and engaging the second blade to hold the same in said pocket.

2. ln a square, a blade having a graduated straight edge, a handle having an edge portion inclined at an obtuse angle to the straight edge, said handle being provided with a recess in Which one end of said blade is secured, said handle having a pocket adjoining the recess portion and being adj acent said blade a second blade having graduations and having one end pivoted in said pocket, whereby the blade may enter the pocket or be Withdrawn therefrom, the second blade being provided With a lateral projection near its pivoted end, the first named blade being provided with graduations vconcentrically disposed With reference to the pivotal connection of the second blade and over which the lateral projection is designed to move, the pivoted end of the second blade being semi-circular, the marginal edge thereof having a series of recesses, and means carried by the handle and provided With a device extending through the Wall of the pocket and engaging any one of said recesses to hold the second blade in various angular positions with reference to the first blade.

In testimony Where-of I have signed my name to this specilication in the presence of tivo subscribing Witnesses.
